How long does it take Loctite to dry?

i've been dropping out my clutch bell a lot lately, (changing the pinion and liner etc.) and noticed that the setscrews that hold the start coupling in place have been flinging the loctite out.

i've been putting the screws in and packing up and going to fly shortly thereafter. i thought it was still holding but just being flung out a little, but today i found that the screws had actually backed out a little bit and the start coupler was loose.

this is blue loctite. does anybody know how long it takes to dry or set up?

To get the best results probably overnight.

Depends on brand and loctite. In general, 24 hours to full strength. Loctite do have some that will cure in 2 hours. They also sell special promotor to shorten the curing time.

But the "blue loctite" isn't very specific, there are at least a few different variation if not more that also uses blue dye.

wow, those are definitely the quickest responses i've ever gotten on RR!

this is the el cheapo kind from the LHS. it just says "liquid thread lock" and the whole rest of the package is in japanese or chinese, or something else i don't understand.

that's a real downer though, needing to wait 24 hours after making a simple bolt-on repair before flying again.

overnight should be fine,yes full strength is about 24 hours,but within 6-8 hours its usually good to go.if you let loctite cure overnite and you still have stuff working loose,you have other issues

looks like i wasn't doing it right then.

oh well, you live and you learn.

at least it wasn't something that brought the heli to the ground before i planned for it to get there!

Wait a while on blue and red, green is almost instant. Depends what you're loctiting really. I would wait overnight for something like your spindle bolts...for some frame hardware, I'd loctite it and fly.

Don't forget to really clean the bolt with alcohol first.

I use blue locktite and I have noticed that the liquid stuff dries quickly whereas the gel locktite takes about 24 hours or so.

It's a complex, costly, glow powered anti-gravity machine!

I've seen some RC cars guys torch the screw with locktight until dry and then install the screw. On the 1 to 1 cars when I replaced the front rotor the screw that came with the kit has dried locktight on the screw for me to screw in.

depends on how much is used

you aint crashin you aint learnin

A good loctite test is if the bolt shears "but" doesn't back off!
Right aadams1278?
At least the threads stayed in tight

that's very true!

i think in the case of the start shaft, it's just a part that spins in a way that can sling the loctite out of the threads.

i say that because i loctited the clutch bolts at the same time as the start coupler bolts.

Are you cleaning them good? and letting the loctite dry long enought?
Cause that was my mistake; not cleaning good enough before using the loctite.

I dont suffer from mental iIlness, I actually enjoy mine!

That's not always true. There are at least three type of green, if not more. 638, 641, 680. I know 680 will require overnight to dry. So, going by color of the loctite is probably the worse way to ID them.

thread lockers doesn't work good on Stainless.

Never heard of that before, I believe as long as one of the mating surface contain metal that will activated the curing process, loctite will cure.

On the note of SS, it's probably not a good idea to use SS on load bearing part as they often (not always) weaker then the normal grade 8 fastener.
